Powerful VOIP test and analyse tool

Supplier News

ANRITSU Corporation , a global provider of operational support solutions for advanced and converged networks, has announced powerful new VoIP features for its InterQuest Analyser, thus expanding the Anritsu portfolio for extensive and effective VoIP monitoring that has become a critical necessity for VoIP service providers.

Anritsu's InterQuest Analyser VoIP provides service providers with a single tool to track network and service quality while providing the means to measure how end customers experience service quality.

It enables service providers to quickly provision, troubleshoot and optimise convergent networks across VoIP and SS7 domains.

Designed with advanced applications for service testing, network monitoring and data acquisition for existing and next-generation networks in a single box, InterQuest Analyzer is a highly efficient tool for testing interoperability in increasingly complex networks while simultaneously automating trivial tasks and reducing operational costs.

"InterQuest VoIP is a powerful tool to help our customers expedite the detection and resolution of problems in their IP and SS7 network, verify QoS of their IP network, and document interconnect SLAs," said Thomas Jensen, vice president and head of the Service Assurance Business Unit of Anritsu. "With this new offering, Anritsu is geared for further expansion into the rapidly growing VoIP monitoring market."

Capable of analysing voice quality, jitter, latency, delay, and packet loss, InterQuest Analyser VoIP can predetermine if voice quality will deteriorate. The product also provides the most cost-efficient way of passively monitoring RTP and RTCP packet flows in the network to ensure that service providers deliver the quality that customers demand.

In addition, InterQuest allows service providers to analyse voice payload quality without the need for costly subjective tests with listeners, by providing objective measurements to produce a MOS (Mean Opinion Score) clarity index for measuring voice quality of calls.

Likewise, InterQuest helps service providers document voice quality SLAs with interconnect partners and customers to meet contractual commitments.

InterQuest's multi-user capability allows up eight users to analyse, simultaneously and independently, different parts of the monitored network, thus optimising work routines while minimising investment in other test solutions.

Key features of the InterQuest Analyser VoIP include:

* Voice quality analysis with MOS, jitter, delay, and packet loss

* VoIP protocol analysis and sequencing SIP & ISUP correlation, SIP/SIP-T, H.323, MGCP, SIGTRAN, RTCP/ RTP, BICC, H.248/MEGACO

* Unique multi-user support for optimized rapid troubleshooting

* Multi-protocol analysis for 'on the spot' troubleshooting

* Call and session tracer


* Real-time live streaming of data to hard disk and historical analysis for highest possible analyser availability

* Advanced statistical processing with intuitive statistical information

* Remote or local operation

* Modular and multi-technology platform for cost-efficient migration to emerging services and technologies

"The new VoIP capabilities of the InterQuest enable Anritsu to meet service providers' growing requirements for VoIP monitoring," said Frost & Sullivan's Jessy Cavazos, program manager, Communications Test & Measurement.

"Going forward, the company is expected to continue to enhance its offering to meet future end-user needs. IP Multi-media Subsystem (IMS) is likely to be one of such targeted areas.

“Already, the new VoIP features being introduced today pave the way for Anritsu to launch dedicated IMS solutions in the future,” he said.

“Anritsu is expected to leverage its leadership in HSDPA/HSUPA base station and user equipment testing for the benefit of the InterQuest platform."
